What are bones made of?
Although bone may seem like a hard, lifeless structure, it is actually very complex and performs many functions. Bone is made of two main components –osseous tissue and collagen. The osseous tissue is made of calcium complexes and is what gives bone its rigidity and strength. Collagen provides the framework of the bone and gives it elasticity and bend. Without collagen the bone would be very brittle. Living cells in bone constantly break down old bone and rebuild it with new bone. In addition to providing the frame to support our bodies, bones produce red and white blood cells and store minerals.
